在导航视图中以编程方式将项目添加到菜单组 [英] Add items to menu group programatically in navigation view

问题描述

我试图务实地将菜单项添加到菜单组，但我发现没有办法做到这一点.我正在使用导航视图并添加了下面提到的菜单:

I am trying to add menu items to menu group pragmatically but I found no way to do that. I am using Navigation View and added below mentioned menu:

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android">

    <item
        android:id="@+id/nav_lang_currency"
        android:title="" />

    <item
        android:id="@+id/nav_home"
        android:title="" />

    <group android:id="@+id/nav_refer" />

    <item
        android:id="@+id/nav_setting"
        android:title="" />

    <item
        android:id="@+id/nav_about_us"
        android:title="" />

    <item
        android:id="@+id/nav_logout"
        android:title="" />

</menu>

一切看起来都很好.

我只想在运行时根据业务需求在 nav_refer 组中添加多个菜单项，但我找不到这样做的方法.

I just want to add multiple menu items in nav_refer group at run-time as per business requirement but I found no way to do that.

我在 SO 上搜索了解决方案，但没有找到办法.

I searched solution on SO but found no way to do that.

请建议我如何在运行时在组中添加多个菜单项.

Kindly suggest me how to add multiple menu items in group at run-time.

推荐答案

要将菜单添加到特定组，请调用此方法 Menu.add(int groupId, int itemId, int order, CharSequence title)>

To add menu to a particular group, call this method Menu.add(int groupId, int itemId, int order, CharSequence title)

    Menu menu = navigationView.getMenu();
    menu.add(R.id.nav_refer, 123, Menu.NONE, "Title1");
    menu.add(R.id.nav_refer, 124, Menu.NONE, "Title2");
    menu.add(R.id.nav_refer, 125, Menu.NONE, "Title3");

重要:最初如果您有空组，那么新添加的项目会出现在底部，要解决这个问题，您需要提及组的订单.为所有组添加一个属性 android:orderInCategory="101"

Important : Initially if you have empty group then newly added items will appear in bottom, to solve this you need to mention orders for groups. add a attribute for all your groups android:orderInCategory="101"
